The Arboretum’s Living Collection contains over 15,000 plants representing some 4,000 kinds of trees, shrubs, and vines, including the Franklin Tree (Franklinia alatamaha), extinct in the wild for over 200 years.

The best part—you can help make it happen! In October, the Arboretum launched TreeVersity, a citizen science project designed to collect information on some 25,000 images of the trees, shrubs, and vines growing across its Olmsted-designed landscape. Since its founding in 1872, Arboretum staff have used photography to help document the plants the institution collects, grows, and preserves for scientific study and horticultural display. Thousands of historical images—captured by famed explorers like Ernest Henry Wilson, Joseph Rock, and Frank Meyer—have long been available for viewing and downloading through the online Image Archive of the Harvard University Libraries. Recently, the Arboretum made thousands of contemporary images of its plants—from Abelia chinensis (Chinese abelia) to Zenobia pulverulenta (honeycup)—available on its own website. This extensive Plant Image Database serves everyone from botanists to armchair plant explorers as a free online tool to aid plant identification, connect plant images and plant information, and promote the study and appreciation of biodiversity.

As threats to biodiversity loom large, researchers and educators must work to foster an awareness and appreciation of plants and the role they play in the biosphere. To aid in this mission, the Plant Image Database serves as a public resource, allowing users to discover a world of botany from their own computers and explore a renowned collection of diverse plants from far corners of the globe. To make this resource more useful to scientists, teachers, students, gardeners, and anyone interested in learning more about plants, the Arboretum has teamed with Zooniverse, the world’s largest online platform for people-powered research. Zooniverse crowd-sources data collection for scientific studies, using the help of hundreds of thousands of volunteers who log on to assist professional researchers.
Using the Zooniverse citizen science platform, TreeVersity volunteers will classify images from the Arboretum’s Plant Image Database by identifying plant parts and other features.

With the support of Arboretum staff members and trained botanists, TreeVersity volunteers will help to expand essential browsing and searching functions of the Arboretum’s Plant Image Database while learning about plant biology and exploring the Arboretum’s collections. TreeVersity launched on Zooniverse with approximately 10,000 images in need of categorization by volunteers. As the project progresses, the Arboretum’s Plant Image Database will have improved functionality as an educational resource—and another important layer of documentation on the Arboretum’s renowned living collections. Founded in 1872 as the first public arboretum in North America, the Arnold Arboretum of Harvard University is a leading center for the study of plants and biodiversity and a cherished 281-acre landscape open to the public year round. One of the most comprehensive and best documented collections of temperate woody plants in the world, the Arboretum promotes the understanding and appreciation of plants through world-class research and educational programs for all ages.
